This mercury ends up in oceans and rivers where it is absorbed by sea life and bioaccumulates
in creatures at the top of the marine food chain.
Mercury makes its way into our waterways and (https://www.scientificamerican.com/article/how-does-mercury-get-into/) bioaccumulates
in the marine food chain.
Statistically, this was evaluated that As(III) bioaccumulates
in the serum blood samples.
In this form, mercury bioaccumulates
in the food chain, working its way into big creatures like whales and tuna.
** Researchers at the University of Sweden found that concentrations of oxazepam in wild-caught European perch were six time that of water, suggesting that this drug bioaccumulates
up the food chain as herbivorous fish eat the algae and are themselves eaten by carnivorous fish.
This is particularly worrisome because 2,4-D is much more toxic than Roundup; it is the seventh-largest source of dioxins (PDF) in our environment, and it bioaccumulates
, meaning it builds up in our bodies and in the environment overtime.
Radioactive cesium, a carcinogen that bioaccumulates
in animal, fish and human tissue, has been found throughout mainland Japan, in fish off the coast of Fukushima (thus closing that industry), and in large migratory fish such as Bluefin tuna off the coast of California.
Larger fish eat the herbivore fish that have eaten the dinoflagellates and the toxin bioaccumulates
until it reaches large predatory fish like barracuda, grouper, snapper, and sea bass.
Mercury in particular bioaccumulates
in the food chain, especially in the fatty tissue of fish, which then winds up on peoples' dinner plates.
Once this mercury gets into the marine food chain, it "bioaccumulates
" in the larger predators.
